Managing Virtual Storage

Virtual storage management is an essential part of any IT infrastructure. As opposed to physical hardware, which it is easy to change out devices or upgrade them to more efficient ones, this kind of storage is more complicated and requires the right management tools to get the most out of it.

Virtualization is the best way to manage complexity. It lets you combine resources and create an effective storage solution that can handle a larger volume of data. Virtualization can be utilized on a number of platforms which include network devices that present centralized storage to your applications, and virtualized storage software that uses the underlying hardware to deliver a single pool of storage to your system.

A network appliance, like uses a physical Fibre Channel SAN (FC) or iSCSI SAN in order to present an array of storage that appears as one logical disk to the server or host. It is able to intercept input/output (I/O) requests and then forwards them to a different physical location on the storage pool, without the host or server knowing what is taking place behind the scene. The mapping granularity affects how quickly meta-data is updated and how much storage space is needed during the migration process, and how quickly a previous physical location can be made available.

Virtualized storage solutions also offer high availability by mirroring data between multiple servers. This means you won’t lose important business data should one of your server nodes fails. The data will be automatically transferred to other servers in the cluster.
